Definitions

  • the invention relates to a sliding element, in particular a piston ring with a coating on at least one tread.
  • Sliding elements e.g. Piston rings, pistons or cylinder liners in internal combustion engines must work over a long service life both with the lowest possible friction and with low wear.
  • the friction which is directly associated with fuel consumption in internal combustion engines, can be kept low by coatings of DLC (diamond-like carbon).
  • layer thicknesses up to 40 ⁇ m can be achieved.
  • layer thicknesses of more than 5 ⁇ m the problem arises that the layer properties, for example with regard to the structure and the composition of the layer, change, so that the required service life is not achieved. This applies in the same way for layer thicknesses of less than 5 microns.
  • PVD coatings based on hard material which usually have chromium nitride. Although such layers have the required wear resistance, but not the necessary low friction coefficients.
  • the DE 10 2008 016 864 relates to a sliding member having a coating having an adhesive layer, a metal-containing DLC layer and a metal-free DLC layer from the inside to the outside.
  • a guide bushing and a method of forming a hard carbon film on the inner surface of the guide bushing in which a hard carbon film of hydrogenated amorphous carbon is formed on the inner surface by a plasma CVD method For example, a guide bushing and a method of forming a hard carbon film on the inner surface of the guide bushing in which a hard carbon film of hydrogenated amorphous carbon is formed on the inner surface by a plasma CVD method.
  • the EP 2 316 983 A1 relates to a sliding element having on at least one surface from the inside to the outside an adhesive layer, a metal-containing DLC layer and a metal-free DLC layer which may be doped with nitrogen.
  • the US 6,354,008 B1 relates to a sliding element comprising, according to one example, a DLC layer and thereon a CN graded-nitrogen layer.
  • WO 2006/125683 A1 a piston ring having, from the inside to the outside, a layer having a group IVB, VB or VIB element, an intermediate layer having a diamond-like nanocomposite composition and a DLC layer.
  • the object of the invention is to provide a sliding element which is further improved with regard to the combination of friction coefficients and wear properties.
  • this has on at least one surface on a coating having an adhesive layer, a metal, in particular tungsten-containing DLC layer and a metal-free DLC layer from the inside out.
  • the coating may in particular be provided on at least one running surface. Alternatively or additionally, however, the coating of at least one flank is possible.
  • the adhesive layer is preferably a chromium adhesive layer.
  • the metal-containing DLC layer comprises amorphous carbon and may be referred to as a-C: H: Me and as the preferred tungsten-containing DLC layer as a-C: H: W.
  • the outermost or top layer also has amorphous carbon and can be given as a-C: H. In the described values, particularly good properties with regard to friction and wear were found.
  • tribological properties can be influenced by a thicker top layer in the direction of a longer service life. However, if it becomes too thick compared to the middle layer, the wear values will deteriorate because the high layer residual stresses reduce the bond strength and this can lead to delamination.
  • the metal-free DLC layer For the doping of the metal-free DLC layer, it was found, in particular for the use of nitrogen, that this advantageously reduces the residual stresses of the layer.
  • the metal-free DLC layer is doped in particular with nitrogen, in particular, as soon as the critical layer thickness is reached. As a result, as mentioned, residual stresses are reduced, so that high layer thicknesses can be formed. Initial tests on a wear test bench have produced good results.
  • Sao Paulo 2000 directed While the coating is formed, at least partially, on at least one running surface of the sliding element, it can extend over the entire running surface and in particular also be completely or partially formed on surfaces which adjoin the running surfaces, such as the flanks of a piston ring and / or at the transition from the tread to the adjacent surfaces.
  • a total thickness of the coating is 5 ⁇ m to 40 ⁇ m. In particular, about 10-20 ⁇ m are preferred.
  • the base material of the sliding element in particular of the piston ring, cast iron or steel is currently preferred. Particularly good properties could be determined for these materials.
  • values of 1400 HV0.02 to 2900 HV0.02 for the metal-free (aC: H, top) DLC layer and / or 800 to 1600 HV0.02 for the metal-containing (aC: H : Me-) DLC layer is preferred, since at these values a good fulfillment of the requirements with regard to layer adhesion and cohesion has been achieved.
  • Both the metal-containing and the metal-free DLC layer can contain hydrogen, which has proved favorable in experiments.
  • the tungsten-containing DLC layer prefferably contains nanocrystalline tungsten carbide precipitates, which further has favorable effects on the properties.
  • the thickness of the adhesive layer which is in particular a chromium adhesive layer, a value of at most 1 ⁇ m is preferred.
  • the adhesive layer is vapor-deposited metallically.
  • a favorable production of the coating according to the invention is further ensured with regard to the metal-containing and / or metal-free DLC layer, if these are formed by means of a PVD and / or PA-CVD method.
  • the two mentioned methods can be combined.
  • nitrogen doping the nitrogen is essentially added as a gas during the process so that nitrogen is deposited in addition to the carbon resulting from the ionization of acetylene in the plasma and the layer is doped as described.
  • a detailed description of the process can be found in the article " Diamond-like Amorphous Carbon "by J. Robertson, Material Science and Engineering R 37 (2002), 129-281 to find.
  • the thickness ratio between the metal-free and metal-containing DLC layers is between 0.7 and 1.5, and / or the ratio of the thicknesses between the metal-free DLC layer and the coating is generally between 0.4 and 0.6.
  • Particularly good wear values could be found if the middle and the top layer have a nearly identical thickness, so that here a thickness ratio of about 1.0, in particular 0.9 to 1.1 or a thickness ratio of the top to the total layer of about 0.5, in particular 0.45 to 0.55 is preferred.
  • Particularly preferred at present is a total layer thickness of, for example, 10-20 microns, wherein the metal-containing DLC layer makes up a thickness of about 40-70% percent of the total, and the metal-free DLC layer has a thickness of about 4.4 to about 7.6 has ⁇ m.
  • the metal-free DLC layer initially very high residual stresses in the overall system, so the coating brings a total, at a layer thickness of the metal-containing DLC layer, the similar to the thickness of the outermost layer can be compensated so that the coating is optimally formed in the combination of strength and toughness.
  • a sliding element coated therewith in particular a piston ring, has good wear resistance.
  • layer thickness ratios between the metal-free and the metal-containing DLC layer of ⁇ 0.7 and / or top to total layer of ⁇ 0.4, the sliding element has a too short life, since the outermost metal-free DLC layer Although a high wear resistance but a has too small layer thickness.
  • the thickness of the metal-containing DLC layer is insufficient to compensate for the residual stresses. This results in premature wear of the DLC layer as a whole, despite the large thickness of the outermost layer or chipping of the DLC layer due to excessive stresses during operation. If the layer thickness of the metal-free aC: H layer layer is to be further increased, this is possible by nitrogen doping, since this reduces the residual stresses and makes the coating process more stable due to the improved conductivity of the top layer. The reduction of the residual stresses further leads to an improved friction behavior.
  • an outer portion of the metal-free DLC layer is doped with nitrogen.
  • a thickness of 10 to 90% of the undoped region is preferred. For this, good results could be found in initial experiments.
  • the figure shows schematically the structure of the coating according to the invention
  • the coating according to the invention on a substrate 8, from the inside to the outside, an adhesive layer 10, a metal-containing DLC layer 12 and a top layer 14, 16, which is a metal-free DLC layer.
  • an outer region 16 is doped with nitrogen while an inner region 14 is not doped with nitrogen.
  • the nitrogen concentration in the doped region is about 15% and is only slightly graded at the transition from the doped to the undoped region. In other words, the nitrogen content falls to 0 over a comparatively small thickness range. However, this course can also be formed well graduated.
  • the properties of the coating according to the invention were tested as follows. Experiments were carried out with 2 piston rings, wherein the top layer of the tread coating is doped to one and not doped in another embodiment.
